Description

Technical Field

[0001] The present application relates to the technical field of plate roller processing, and in particular to a grinding device for gravure plate roller production. Background Art

[0002] Currently in the production process of gravure printing rollers, after rough processing and forming, the rollers will be placed in a grinding device, and the surface of the rollers will be polished by the grinding head on the grinding device to make the surface of the rollers smooth.

[0003] The existing Chinese patent document with publication number CN220680435U discloses a coolant splash-proof structure for a grinder. The background technology discloses a grinding device, including a workbench, a grinding groove is provided on the workbench, a plate roller is installed in the grinding groove, and a sliding base is provided on the workbench, a grinder and a cold water pipe are installed on the base, the grinder is used to grind the plate roller, and the cold water pipe is used to spray water on the plate roller to cool down and reduce dust.

[0004] For the installation of the plate roller, a top cone capable of lateral movement is usually set at both ends of the workbench. The top cone is inserted into the end of the plate roller to limit the position of the plate roller. After the plate roller is ground, the top cone is moved away from the plate roller to take the plate roller away. However, when the plate roller is ground, it is only supported by the top cone, so that the plate roller is suspended relative to the workbench. Therefore, after the top cone leaves the plate roller, the plate roller is easy to fall into the grinding groove. The collision between the plate roller and the workbench is easy to damage the plate roller, affecting the processing quality of the plate roller. Utility Model Content

[0009] A support frame, located in the water receiving tank and capable of moving up and down relative to the machine body, for supporting the plate roller; and

[0010] A linkage member is connected to the mounting seat and cooperates with the support frame, so that when the top cone member clamps the plate roller, the support frame moves downward away from the plate roller, and when the top cone member is separated from the plate roller, the support frame supports the plate roller.

[0011] By adopting the above technical solution, when the top cone leaves the plate roller, the supporting frame is driven to move through the linkage member, so that the supporting frame supports the plate roller, so that the operator can remove the plate roller from the supporting frame, reducing the possibility of the plate roller falling and colliding with the workbench.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The present application embodiment discloses a grinding device for producing a gravure printing plate roller 1. Figure 1 and Figure 2 The grinding device for producing the gravure printing plate roller 1 comprises a machine body 2, a clamping assembly, a support frame 5 and a linkage. The clamping assembly is arranged in the machine body 2 to clamp the plate roller 1, the support frame 5 moves up and down in the machine body 2 to support the plate roller 1, and the linkage is matched between the clamping assembly and the support frame 5 to drive the support frame 5 to support the plate roller 1 when the clamping assembly is separated from the plate roller 1.

[0040] Reference Figure 1 and Figure 3Specifically, the machine body 2 includes a workbench 21 and a support base 22. The workbench 21 is square, and has two support bases 22. The two support bases 22 are respectively fixed at two ends of the workbench 21 that are far away from each other, and the bottom surface of the support base 22 extends downward beyond the bottom surface of the workbench 21, so that the workbench 21 is suspended relative to the ground. The workbench 21 has a base 15 that moves along its length direction. The base 15 is equipped with a grinder 16 and a cold water pipe 17. The mechanism for the workbench 21 to drive the base 15 to move is not shown in the figure. It can be a motor and a screw, or it can be a transmission belt. The way the grinder 16 and the base 15 move are all existing technologies, which will not be described in detail here.

[0041] A water receiving trough 3 with an opening facing upward is provided on the workbench 21 , and a drainage pipe 14 extending from the bottom of the workbench 21 to the outside of the workbench 21 is fixed to the lower surface of the workbench 21 . The drainage pipe 14 is connected to the water receiving trough 3 , and the water stored in the workbench 21 can be discharged through the drainage pipe 14 .

[0042] Reference Figure 2 The clamping assembly includes two sets of matching groups 4, which are mirror-symmetrically installed on opposite sides of the workbench 21 along the vertical center line of the workbench 21. Each set of matching groups 4 includes a mounting seat 41, a top cone 42, a rotating member 43 and an adjusting member 44.

[0043] Reference Figure 2 and Figure 4 Specifically, the mounting seat 41 is located in the water receiving tank 3, and the bottom surface of the mounting seat 41 abuts against the inner bottom wall of the water receiving tank 3. The adjusting member 44 is a cylinder, and the seat of the cylinder is installed and embedded in the supporting seat 22. The piston end of the cylinder extends into the water receiving tank 3 along the length direction of the workbench 21 and is connected to the mounting seat 41. When the piston end of the cylinder is extended and retracted, it drives the mounting seat 41 to move in the water receiving tank 3 along the length direction of the workbench 21.

[0044] The rotating member 43 is a rotating motor installed in the mounting seat 41 , and the output end of the rotating motor extends out of the mounting seat 41 from the side of the mounting seat 41 away from the connected cylinder, and the axial direction of the output end of the rotating motor is parallel to the length direction of the workbench 21 .

[0045] Reference Figure 4 and Figure 5 The top cone 42 includes a connection seat 421, a cone 422 and a reset portion 423. The connection seat 421 is located on the side of the mounting seat 41 away from the cylinder and is connected to the output end of the rotary motor. The cone 422 is conical and located on the side of the connection seat 421 away from the rotary motor. The side with a smaller outer diameter of the cone 422 is farther away from the corresponding connection seat 421 than the side with a larger outer diameter of the cone 422. A space for placing the plate roller 1 is formed between the cones 422 located at both ends of the workbench 21.

[0046] The connection seat 421 includes a connection portion 4211 and an extension portion 4212. The connection portion 4211 is connected to the output end of the rotating motor. The extension portion 4212 is integrally formed on the side of the connection portion 4211 away from the rotating motor, and the extension portion 4212 is in the shape of a square rod with a length extending along the axial direction of the output end of the rotating motor. A connection groove 13 is coaxially provided at the end of the cone 422 for the extension portion 4212 to be inserted and slid along the axial direction of the cone 422, and the cone 422 is coaxially arranged with the output end of the rotating motor. In addition, a stroke portion 10 protrudes on the outer wall of the extension portion 4212, and a stroke groove 11 is provided on the inner wall of the connection groove 13 for the stroke portion 10 to slide. The stroke groove 11 does not pass through the end of the cone 422, and the direction in which the stroke portion 10 slides in the stroke groove 11 is parallel to the axial direction of the cone 422.

[0047] Reference Figure 4 and Figure 5 The reset part 423 is a spring, and the reset part 423 is located in the connection groove 13, and the two ends of the reset part 423 that are far away from each other are respectively connected to the extension part 4212 and the inner wall of the cone 422, so that the reset part 423 gives the connection seat 421 and the cone 422 an elastic force to move away from each other. When the reset part 423 drives the connection seat 421 and the cone 422 to move relatively until the stroke part 10 abuts against the end of the stroke groove 11 close to the rotating motor, the reset part 423 is still in a compressed state, and the distance between the connection part 4211 and the cone 422 is the largest. When the connection part 4211 abuts against the end surface of the cone 422, the distance between the connection part 4211 and the cone 422 is the smallest.

[0048] Reference Figure 1 and Figure 5 When the plate roller 1 is installed in the workbench 21, the piston ends of the cylinders in the two matching groups 4 are extended, driving the mounting seats 41 in the two matching groups 4 to move towards each other, and the cones 422 in the two matching groups 4 are respectively pressed into the opposite ends of the plate roller 1, and the connecting part 4211 and the cone 422 are pressed tightly against each other, so that the cone 422 and the plate roller 1 are pressed tightly, so that when the rotating motor drives the connecting part 4211 to rotate, the cone 422 rotates together with the plate roller 1, so that the grinder 16 can grind the plate roller 1 along the circumference of the plate roller 1.

[0049] Reference Figure 2 and Figure 6The support frame 5 is located in the water receiving trough 3 of the workbench 21 and between the two mounting seats 41. The support frame 5 includes a support frame 51, an abutting roller 52, a guide portion 53 and an abutting portion 54. The support frame 51 is a planar frame, and the surface of the support frame 51 extends in the horizontal direction. There are four abutting rollers 52, and the four abutting rollers 52 are installed on the upper surface of the support frame 51 in a horizontal and vertical array by bolts, and the length direction of the support frame 51 and the axial direction of the abutting roller 52 are parallel to the length direction of the workbench 21. When the support frame 5 moves upward, the plate roller 1 can be abutted between the four abutting rollers 52 to support the plate roller 1.

[0050] There are four guide parts 53, which are fixedly installed at the four corners of the support frame 51, and each guide part 53 is cylindrical with an axis extending vertically downward. The workbench 21 is fixed with a guide seat 12 corresponding to the guide part 53 at the bottom wall of the water tank 3, and each guide part 53 slides up and down in the corresponding guide seat 12 to guide the up and down movement of the support frame 51.

[0051] There are two abutting parts 54, which are respectively fixed at two ends of the support frame 51 away from each other. Each abutting part 54 is in the shape of a rod extending vertically downward, and a ball 9 protruding from the bottom surface of the abutting part 54 is rotatably disposed at the bottom end of the abutting part 54.

[0052] Reference Figure 1 and Figure 2 The linkage member includes a linkage seat 6, which corresponds to the mounting seat 41 one by one. The linkage seat 6 is fixed to a side of the corresponding mounting member facing the support frame 51, and the bottom surface of the linkage seat 6 abuts against the inner bottom wall of the water receiving tank 3.

[0053] Reference Figure 4 The upper surface of the linkage seat 6 is formed with an inclined surface 7 and a retaining surface 8. The inclined surface 7 gradually inclines upward in the direction close to the support frame 51. The retaining surface 8 is a horizontal plane and continues to the side of the inclined surface 7 close to the support frame 51, so that the height of the retaining surface 8 is flush with the highest height on the inclined surface 7. The two abutting portions 54 on the support frame 51 are respectively abutted on the upper surfaces of the two linkage seats 6 through the balls 9, so that the linkage seat 6 supports the support frame 51, and the support frame 51 is subjected to the downward gravity of itself so that the balls 9 always abut against the upper surface of the linkage seat 6.

[0054] Reference Figure 4 and Figure 5 When the two cones 422 clamp the plate roller 1 together and the connecting part 4211 and the extending part 4212 are pressed against each other, the ball 9 abuts against the inclined surface 7 and is close to the lowest point of the inclined surface 7. At this time, the abutting roller 52 is located below the plate roller 1 and is separated from the plate roller 1, so that the plate roller 1 does not interfere with the abutting roller 52 when it rotates and grinds.

[0055] When the grinding of the plate roller 1 is completed, the cylinder drives the mounting seat 41 to move away from the support frame 51. During the process, the connecting portion 4211 first moves away from the support frame 51, and at the same time, the linkage seat 6 moves away from the support frame 51 to drive the abutment portion 54 and the support frame 51 to move gradually upward together, and the cone 422 is still connected to the plate roller 1 to limit the plate roller 1.

[0056] When the distance between the connecting portion 4211 and the cone 422 is the largest, the contact portion 54 moves to the holding surface 8, and the support frame 51 moves until the contact roller 52 contacts the plate roller 1. Then, the mounting seat 41 continues to move away from the support frame 51 to a retracted state, so as to drive the cone 422 to separate from the plate roller 1, and the contact portion 54 still contacts the holding surface 8, thereby maintaining the state in which the contact roller 52 supports the plate roller 1. In this state, the operator takes out the plate roller 1.

[0057] The implementation principle of the grinding device for producing a gravure printing plate roller 1 in the embodiment of the present application is as follows: when the plate roller 1 is being ground, it is pressed and clamped by the cones 422 at both ends of the workbench 21, and at this time, the abutting roller 52 is separated from the plate roller 1. After the grinding of the plate roller 1 is completed, the cylinder drives the mounting seat 41 and the linkage seat 6 to move away from the support frame 51, so as to push the support frame 51 upward through the abutting portion 54, so that the abutting roller 52 abuts against the plate roller 1 to support the plate roller 1, so that after the cone 422 is separated from the plate roller 1, the plate roller 1 is supported by the abutting roller 52 and is not easy to fall and collide with the workbench 21.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
